The subject of our illustration, which is an endemic 
species in the Canaries, is, according to Dr. Schenck, the 
most characteristic plant of the Alpine region of Teneriffe, 
where it is abundant between 6,000 and 9,000 feet above 
sea-level, and is to be met occasionally even at 10,000 feet. 
Here it forms a compact globular bushy shrub about five 
feet in height, and nearly as much across. Dr. Christ, 
in consequence of its peculiarly characteristic nature, speaks 
of it as the “ Alpenrose,” or the “ Krummholz of the Peak.
